How to measure the temperature of a high-voltage busbar
Non-contact infrared sensors continuously monitor busbar temperature from a safe distance within cabinets, avoiding physical contact or complex insulation requirements. They detect early signs of overheating, allowing preventive maintenance. Temperature monitoring in high-voltage busbar systems is vital for preventing faults, yet difficult due to electrical hazards, limited accessibility in switchgear cabinets, and interference risks in traditional contact-based methods. Due to busbars conducting high currents, small rises in temperature can be indicative of faults. Temperature rise testing is one of the recommendations of IEC 61439; our system for monitoring switchgear and busbars is easily integrated with new installations or retrofitted to existing infrastructure. Switchgear and busbars can be constantly and comprehensively monitored for temperature rises. Calex non-contact infrared temperature sensors, in conjunction with a centralised monitoring system, are an ideal way of measuring these temperatures.

Tunnel Temperature Sensing Optical Cable Splicing
In this article, we present a tunnel monitoring approach based on distributed fibre optic sensing (DFOS), which delivers hundreds of strain and temperature sensing points inside the structure and gives completely new information about the behaviour of the tunnel lining. Accordingly, the health status of the tunnel is dynamically grasped, which is of great significance to ensure the. Distributed Temperature Sensing (DTS) systems provide temperature information for accurate thermal monitoring, fire detection, and condition assessment by utilizing standard fiber optic cables. This study presents a state-of-the-art review of the DFOS applications for monitoring and. Today, modern monitoring systems allow reliable condition monitoring of tunnels using optical sensor technology, based on fiber Bragg technology. Tunnels are at the core of our infrastructure., has not been put into practical use, because it is difficult for conventional point type temperature sensors to.
